PurposeRadiographic indications for primary splenectomy (PS) in blunt splenic injury (BSI) after radiographic diagnosis are unknown. Improved understanding of radiographic characteristics of patients requiring splenectomy will help to appropriately triage patients to PS or non-operative management (NOM).MethodsA retrospective, single-center review was performed of BSI diagnosed with computerized tomography (CT). Patients undergoing splenectomy prior to CT diagnosis were excluded.ResultsBSI was identified in 195 patients. On logistic regression, only subcapsular hematoma presence (OR 7.521, p = 0.002) and left upper quadrant hemoperitoneum (OR 6.146, p = 0.03) were associated with need for PS, while splenic laceration length, number of pseudoaneurysms (PSA), and active contrast extravasation (NS for all) were not.ConclusionsNeed for PS is predicted by extra-parenchymal pathology in subcapsular hematoma and hemoperitoneum. Splenic vascular injuries through PSA and active contrast extravasation do not predict the need for PS and can be considered for NOM.
